Joining Trailer, Visual, and Announcement

The First Generation Did Not Stop at Six

UltraLMTM initially introduced six creators who held debut streams across October 5 and 6. Only hours after that rollout concluded, the brand revealed a third day featuring Alpha Azur and Kohaku Uru.

They are not presented as a second generation. The official website directly lists Alpha as Creator 07 and Kohaku as Creator 08 within the existing first-generation roster.

Alpha Azur Joins After Years as a Streamer

UltraLMTM describes Alpha Azur as a game-loving streamer leaving the forest that helped him grow to pursue a new dream, with fishing among his hobbies.

Alpha announced that he was moving from independent activity to becoming an UltraLMTM-affiliated VTuber. PANORA notes that he has streamed since around 2016 and previously competed in the PUBG scene.

Kohaku Uru Brings a 1,500-Year-Old White Fox Persona

Kohaku Uru's official profile describes her as a 1,500-year-old white fox deity who refers to herself as “kami.” Alongside gaming, she plans to continue trying new activities at her own pace.

She was already active as a VTuber before joining the brand, including League of Legends streams, making the October 7 broadcast her first stream under UltraLMTM rather than the beginning of her overall creator career.

Back-to-Back Streams Followed by a k4sen Program

Alpha takes the first slot at 19:00 JST, running for 30 minutes. Kohaku follows from 19:30 to 20:00 JST.

UltraLMTM will then hold an official program with k4sen, joined by Takaya Special and Shinichiro Inui, featuring segments connected to the two newly added members.

UltraLMTM Now Has Eight Creators

GANYMEDE founded UltraLMTM in September 2025 with k4sen as producer, before the project moved into its full debut phase one year later.

The brand presents its development through “Patches,” borrowing the language of online-game updates for creator activities, events, programming, and worldbuilding. Alpha and Kohaku's arrival expands the roster just as Patch1.0 begins.

Why This Matters

1) The roster expanded immediately after the initial debuts

Rather than waiting for another generation, UltraLMTM has enlarged its first-generation lineup from six to eight.

2) Both additions already have creator experience

Alpha Azur and Kohaku Uru bring existing streaming histories, making the announcement a new phase in their careers rather than a start from zero.

3) The Patch concept can support surprise additions

UltraLMTM is designed around an evolving update model, and this sudden roster expansion shows one way that structure can be used.
